Embodiment Construction

[0040] Such as figure 1 Shown is the function iteration diagram of the present invention, and the main functions include three major aspects: the above-mentioned task block simulation analysis, the above-note task block verification and the task planning modification and inversion function.

[0041] The main function of the above-mentioned task block simulation analysis is to perform on-board mission simulation analysis on the mission data blocks generated by the ground mission planning system. The sequence includes the command name and command parameters, and the start execution time of the command includes Beijing time, Greenwich mean time, UTC time and attitude control satellite time. At the same time, the system inverts the format of the above-noted mission data block into format information that can be recognized by the on-board system. The format inversion mainly includes the format content, the on-board codeword corresponding to the format content, the description of th...

Abstract

The invention provides an agile satellite mission interpretation closed loop simulation verification system and method. Efficiency of key links of simulation verification and inversion modification of current agile satellite mission planning can be effectively enhanced, and correct implementation of agile satellite mission planning can be guaranteed. With application of the agile satellite mission interpretation closed loop simulation verification system and method, firstly a satellite mission host mission interpretation function is simulated, a conventional satellite mission test bed is replaced, mission blocks are interpreted into instruction sets which can be performed by a satellite mission host and information of instruction names, parameters and performing time can be visually displayed in a form mode, and mission block interpretation results are automatically interpreted and abnormal information is outputted so that noting of error mission blocks on satellites can be avoided; secondly, the parameters in the mission blocks and mission block settings can be modified and the mission blocks can be generated again by the system, and iterative analysis is performed on the mission blocks so that correctness can be guaranteed, the risk caused by manual arrangement of the mission blocks can be avoided, and mission block generation efficiency and reliability can be enhanced; and finally the interpretation results of the finally generated correct mission blocks are compared with action sequences generated by a mission planning system so that correctness and rationality of mission planning can be verified.

Description

technical field [0001] The invention relates to an agile satellite task interpretation closed-loop simulation verification system and method. Background technique [0002] With the gradual deepening of the application of aerospace images in various industries, users have higher and higher requirements for image data information, and need a faster and more flexible image generation mode, which not only has great commercial application value, but also has important military applications. Therefore, improving attitude maneuverability has become a development trend of earth observation satellites, and agile satellites are created to meet this demand. The attitude maneuverability of agile satellites is much higher than that of traditional earth observation satellites. It can not only image through roll maneuvers, but also through pitch maneuvers. With the help of this large-scale rapid attitude maneuverability, it can achieve rapid response and multiple Mode imaging function, ho...
